A network system comprising a service control device (SEM); and at least one application execution device (AEE); wherein the service control device (SEM) is adapted to receive a service request, to select an appropriate application execution device according to the service request, and to invoke the selected application execution device, and wherein the application execution device (AEE) is adapted to perform the service requested by the service request. A corresponding network control method is also provided. According to the invention, a flexible service architecture is possible.

Internet protocol based service architecture

A method to authenticate a mobile station B in a mobile network, so that the mobile station B is authenticated and an encryption key is agreed between mobile stations A and B using user data exchange during call setup. More specifically the mobile station B is authenticated by the mobile station A constructing and sending to the mobile station B a message M, the mobile station B receiving the message M, constructing and sending a message Mto the mobile station A, the mobile station A receiving the message M, checking the validity of the information in the message M, if the information is verified valid the mobile station A accepting to share a shared encryption key K with mobile station B, the mobile station A constructing and sending the message Mto the mobile station B, the mobile station B receiving the message Mand verifying the validity of the information, if the information is valid the mobile station B accepting the sharing of the shared encryption key K with the mobile station A.

Method to authenticate a mobile station, a communications system and a mobile station

A method and a wireless telecommunications system, a message service center and a mobile station implementing the method for transmitting messages between a mobile station and a second party. The method of the invention includes delivering messages irrespective of the presentation thereof: delivering messages through the same message service center irrespective of the content type and employing the same protocol between the terminal and the message service center for all messages. The content type indicates the presentation of the message contents which may include test, speech, images, video images or various combinations thereof.
